MACHINE FOR CUTTING BUNGS.

Specification of Letters Patent No. 22,101, dated November 16, 1858.

T0 all whom t may concern.'

Be it known that we, JAMES LYON and GEORGE H. BRADY, of the city andState of New York, have invented, made, and applied to use certain newand useful Improvements in Machinery for Outting Bungs and SimilarArticles; and we do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same,reference being had to the annexed drawing, making part of thisspecification, wherein- Figure l, is a side elevation and Fig. 2, is afront view of our said machine. Fig. 3, is a view of the face plate thatmoves the tools, and Fig. 4, is a face view of the chuck and toolstocks.

Similar letters denote the same parts.

The nature of our said invention consists of a revolving face chuckcarrying adjustable stocks through which cutters are slid. and forceddown Vonto the article to be cut, or withdrawn therefrom by means of aface plate acting on the ends of said cutters. le also mak-e use of arevolving cutter to finish off the outer end of the bung. l

ln the drawing A, is a frame which may be sustained in a vertical orhorizontal position by suitable nieans,.but we prefer the formerposition; on this frame boxes B, B, are provided that sustain thevertical shaft C, which is to be revolved when in use by the pulley D.

On the lower end of the shaft O, a face plate or chuck E, is attac-hed,and for forming bungs the surface of this chuck is beveling or conical.,at an angle the reverse of that given to the beveled sides of the bung.This chuck is provided with radial slots receiving the slides ZJ, whichcarry the stocks c c of the cutters cl, (Z. These stocks are adjustableso as to vary the size of the bung produced by forcing said cutters CZ,(l, into a plank or other piece of wood resting on the bed G. In orderto slide the cutter I stocks c, c, through their slides b, b, and

stocks c, c, so that said cutters (Z, d are both forced down andwithdrawn by the motion of said face plate, and the convergence of saidcutters is allowed for by the sliding of said cutter heads in the slidesm, x. To give motion to this face plate F, we provide a fork p, on therod o, that receives motion from the cam a, that is revolved by theshaft c' and wheel m; g is a guide rod and u is a spring keeping theroller on the end of rod 0, against cam a, and also drawing the cuttersback when the cam a, permits thereof.

The bed G is to receive a motion suicient for entering and withdrawingthe piece of wood to be operated on, and for this purpose any suitablemeans may be employed; we however have shown a cam r which acting on aroller and rod s communicates the necessary motion to said bed G,-thespring z, being used to compensate for any difference in thickness, andto keep the wood up to the revolving tool f that sets on the spindle e,at the end of the shaft C. This facing tool f' is provided with aconical center point which acts to steady the material while beingoperated on. The cam 1^ is afliXed on the shaft lz, and may receive amotion from the wheel mi, by the rod Z, and crank 7c.

It will be apparent that this apparatus might be used for cutting bungholes in barrels, although primarily adapted to forming bungs; and alsothat the angle at which the tools cut the sides of the bung or plug, maybe varied according to the inclination of the cutter d, and stock c.

What we claim and desire to secure by Letters Patent is The cutters d,(Z, and stocks c, c, sliding in the adjustable blocks b, Z9, that arerevolved by the face plate E, and which cutters d, CZ, are projected bymeans of the disk F and act to cut a tapering bung substantially asspecified.

In witness whereof we have hereunto set our signatures this fifteenthday of October 1858.
